DUST COLLECTOR.

Application filed na 5,

To all whom it may concern:

Be it known that I, GEORGE P. MC- SWEENEY, a citizen of theUnited States, residing at Memphis, in the county of Shelby and Stateof Tennessee, have invented certain new and useful Improvements in Dust Collectors, of which the following is a specification.

This invention has reference to an improved dust collector and the principal objcct is to generally improve upon devices of this class, by providing one of comparative simplicity and durability, the construction being such that it is exceedingly practical in operation, and inexpensive to both the manufacturer and the user.

The primary structural feature of the present invention is the provision of a plurality of internal radially spaced cones of truncated form, which are arranged in a manner to more effectively separate the dust particles from the air, whereby to free the air of dust in a manner more easy and ef- "ficient than has heretofore been contemplated.

The particular details for accomplishing this result will become apparent from the following description and drawing. In the accompanying drawing, forming a part of this application, and in which, like numerals are employed to designate like parts throughout the same:

Figure 1 is a central vertical section through a dust collector constructed in accordance with the present invention.

Figure 2 is a top plan view of the same.

Referring to the drawing in detail, the reference character 1 designates an outer casin which is provided with an upper cylin rical portion 2 and a reduced portion 3, which serves to concentrate and cause the dust particles to gravitate downwardly into the outlet pipe 4. An opening is formed in one side of the upper cylindrical portion and an air intake 5 connects the disc to conduct air into the separator. As before indicated, the distinction of the invention is the provision of a plurality of supplemental and internalcones 6, 7 and 8. It will be noted that the apices of these cones are truncated,

and that the cones, are graduated in size from the smaller inner cone 6 to the outer larger cone 8.' They are thus disposed in concentric radiall spaced relation and terminate on vertica ly spaced planes. A tortuous air passage'is thus provided, which serves to completely separate the dust particles from the air, causing them to gravitate downwardly, into the restricted lower portion 3 of thecasing. Connected to the top of the casing are appropriate air'outlets 9. In practice, there may be any 'desired number of these outlets to retard or accelerate the discharge of air as desired. It will also be noted that\an opening 10 is provided at the top of the device, tofacilitate the circulation of air. Furthermore, a plurality of legs 11 are connected to the 8 and depend therefrom and serve to support a disk 12. The disk is disposed at a point to provide a comparatively restricted annular discharge spa e 13, between its periphery and the inner surface of the wall of the casing.

From the foregoing description, it is obvious that the infiowmg air enters the casing, through the intake pipe 5, follows a tortuous path compelled by the presence of I the supplemental cones 6 to 8, and escapes through'the outlet 10. During its passage through the device, the particles of dust are separated therefrom, wardly into the casing and are discharged through the pipe 4, whichle'ads to any ap-. propriate place of deposit.

ersons familiar with devices of this kind will be able to obtain a clear understanding of the same, after considering the description, in connection with the drawing. Therefore, a more lengthy description of the same is probably unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to, if desired.

I claim: I

A dust collector comprising a casing having an upper cylindrical portion and a reduced and tapered lower portion terminatand gravitate down- Undoubtedly,

ing in a dust discharge, an air supply pipe connected with said cylindrical portion, a plurality of internal separating cones disposed in said casing, said cones having their 5 apices truncated and being of varying lengths, legs connected to and depending from the outermostinternal cone, and a disk supported on the lower ends of said legs and having its peripheral edge spaced from the adjacent wall of said casing. 10

In testimony whereof I aifix my signature.

GEORGE P. MGSWEENEY.
